Science Experiments

Robert A. Millikan conducted these experiments. His discoveries are instrumental to atomic and particle theory.

In terms of microwaves themselves, the dangers are largely limited to the effects of the heat generated when the microwaves interact with human tissue. The greatest risk of high power microwaves is to the eyes, where the heat cannot be quickly removed by the cooling effect of the blood supply. Hence, corneas are particularly vunerable to micriwave heating. The testes in males are also vulnerable, although it is generally less likely that they will be exposed to microwaves.

In terms of microwave oven use, there are two principle dangers - The first is superheated liquids (liquids above their normal boiling point), which can flash-boil when, for example, instant coffee, sugar, or any other power is added. The second (and at one time the cause of most microwave oven accidents) comes from exploding unbroken eggs, as the yolk heats so efficiently that, even if the egg doesn't explode in the microwave, it can explode in the user's face when it is removed from the microwave oven.

There are no reliable reports of adverse health effects from low-level microwaves from such things as mobile phones or telecom masts.

a top loading balance is use to weigh solid material when a precision of 0.1 g is adequate. If you want to get more accurate mass measurements or small amounts it's better to use an analytical balance. Also, analytical balances have capacity to weigh up to about 200 g with resolution from 0.0001 to 0.00001 g. Top loading balances, on the other hand, can weigh in excess of 5 kg with resolution from 1 to 0.001 g. As capacity increases, the number of decimal places normally decreases.

When hot water is poured into a drinking glass, the temperature difference between the hot water and the glass can cause uneven expansion, leading to stress in the glass material. If the stress exceeds the glass's structural integrity, it can result in the glass breaking. Rapid heating can also cause thermal shock, further increasing the likelihood of the glass breaking.

The temperature coefficient of a thermistor is a measure of how much its resistance changes with temperature. It is typically expressed in units of percent resistance change per degree Celsius. Negative temperature coefficients mean the resistance decreases as temperature increases, while positive coefficients mean the resistance increases with temperature.

Examples of chemical changes caused by light energy include photosynthesis in plants, which converts carbon dioxide and water into glucose and oxygen using light energy, and photodegradation of plastics, where light exposure breaks down the polymer chains, leading to degradation.

in law of conservation of energy

ENERGY IS CONSERVED and in law of conservation of momentum MOMENTUM IS CONSERVED.

There's not similarity in these two laws.

expect that in both laws , one quantity is conserved.

When sucking an egg into a bottle, the pressure inside the bottle decreases as the egg blocks the opening. Without enough pressure to push the egg through the bottleneck, the egg remains stuck inside the bottle.

You can find rocks, gems, fossils, and minerals in various locations in Alberta such as the Rocky Mountains, Badlands, and along riverbeds. Popular locations include Dinosaur Provincial Park, Canmore, and Jasper National Park. Make sure to obtain any necessary permits or permissions before collecting.

Yes because velocity vector is got by the product of acceleration vector and time which is scalar. v = a t

(Except when you toss a ball upward, and until it reaches the top, it has upward velocity

and downward acceleration. But in all other situations except for that one.)

(And except when a yo-yo or an artificial satellite is moving in a circle, and its velocity

is always tangent to the circle but its acceleration is always toward the center of the

circle. But definitely in all other situations except for that one.)

Mass is a measurement of the amount of matter in an object, while force is the interaction that causes an object to accelerate. Energy is the ability to do work, where work is done when a force moves an object over a distance. The relationship between mass, force, and energy is intertwined in equations such as F=ma (Newton's second law) and E=mc^2 (relating mass and energy).

Power. It is the amount of work done per unit of time and is typically measured in watts or horsepower. The higher the power, the faster work can be done by the machine.

maybe force

A freakin plus

Some examples of translucent objects are frosted glass, wax paper, stained glass windows, and certain types of plastics. These materials allow light to pass through them, but they are not completely transparent.

Basic equipment

1.Cd players / turntables

2.Mixer

3.Speakers (Active - not needing a amp or Passive - Needing a powered amp)

4.Amp (If needed)

5.Headphones

6.Microphone

7.Wiring

a) phono leads - red and white wires from CD player to mixer

b)Xlr - from the mixer to the amp or speakers

c)Speakon leads - from the amp to the speakers

and not forgetting.....

8.Music!

The variable in an experiment that remains the same is known as the control.

The term that refers to the power of a microscope is "magnification." Magnification indicates the degree to which the image of an object is enlarged when viewed through a microscope, providing details that may not be visible to the naked eye.

Soft surfaces absorb quite a lot of the energy (by deforming) that the ball uses to spring back up, whereas hard surfaces don't absorb that energy (because they don't deform), and so the energy is used to deform the ball, which is then converted back into kinetic energy and the ball bounces.

an exaple of bias is: you want to see a movie with you friends but you're friends dont want to go. so you tell them an interesting part in the movie that they will like. you only give partial information so they will make the choice you want. i know this and im only 13=p

Yes, we often use them for washing (dishes, ourselves, cars, etc...). In the environment, they are typically found in the ocean, where they filter the water. They are an animal, not a plant, that is an important part of their ecosystem. In fact, they are the simplest of all animals.

The inert gas inside the light bulb prevents the filament from catching fire by creating an oxygen-free environment. This inhibits combustion reactions that would ordinarily allow the filament to ignite.

The variable part of the experiment that is being tested is called the independent variable. It is the factor that is manipulated or changed by the researcher to see its effect on the dependent variable.

To convert km into m, you multiply by 1000. Since there are 1000 m in one km, there are 732 m in 0.732 km.

Electric current involves the flow of electrically charged particles, such as electrons, through a conductor. Magnet current, on the other hand, refers to the flow of magnetic field lines through a material, typically induced by an electric current passing through a wire. Magnet current is associated with the movement of magnetic fields, whereas electric current is associated with the movement of electric charges.
